SPECIFICATION forming part of Letters Patent No. 645,973, dated March27, 1900.

Application filed January 6, 1900. Serial No. 535. (No model.)

To 'all whom, it may concern:

Be it known that I, FRANK RHIND, a citizen of the United States,Aresiding at No. l Broad street, Bridgeport,Faireld county,Connecti cut,have inventeda new and usefulImprovement in Lamp-Brackets, ot' which thefollowing is a specification.

My invention relates to the class of brackets used to detachably'secu rea lamp to a cycle or other vehicle. It is intended to facilitate thedetachment of such lamps when desired and to prevent their accidentaldisplacement.

In the accompanying drawings, Figure I, partly in elevation and partlyin vertical secy tion, shows a bracket embodying my invention. Figs. IIand III are top plan and horizontal sectional views of a part of thedevice shown in Fig. I. Fig. IV, partly in front elevation and partly insection, shows the same part. Figs.V and VI, in vertical and horizontalsection, respectively, show a modification.

l designates a lamp-body; 2, a lug formed with 'central aperture 21 andslot 22; 3, a bracket provided with clamping-plates 3l 32, which havelugs 33 34; 4, a bolt consisting of body 41, shoulder42, and head 43,and 5 a nut.

In the example of my invention illustrated in Figs. I to IV of thedrawings the lampbody l, indicated in dotted lines, may be of anydesired construction. To the body 1 is secured a bracket-lug 2, providedwith a central aperture 21 and with a slot 22, leading radially fromsuch aperture and of a Width less than the diameter thereof. The portionof the device so far described is similar to that shown in my formerUnited States patent, No. 621,374.

The vehicle engaging portion 3 of the bracket' consists, as shown, of apair of jaws adapted to engage a portion of a cycle or other vehicle, tothe front end of which is adjust-ably connected a pair of clampingportions 31 32, shown as substantially circular plates adapted toembrace the lug 2 on the lamp 1. Passing centrally through the plates 3132 and engaging in a nut 5, secured to the plate 31, as shown, is a bolt4, the body portion 41 of which is of a diameter to pass through theslot 22 in the lug 2. A cylindric shoulder 42 on the bolt 4 is of adiameter to fairly fit the aperture 21 of the lug 2. The

shoulder 42 may, if desired, be a -loose sleeve Inturned lugs 33 34 onthe plates 31 3,2, ref

spectively, are clearly shown in Figs. I and IV. It will be seen thatthese are formed by bending inward a tongue of metal from eacli 6oplate. They are of a width to substantially fit the slot 21.

The operation of my device will be readily understood from an inspectionof the drawings. It is clear that when the bolt 4is tight- 65 ened up tothe position shown in Figs.-I and II the lug 2 will be irml'y heldbetween the plates 31 32 and will be prevented from turning therein bythe engagement of the lugs 33 34 in the slot 21. It is also clear thatno jar 7o or vibration can act to disengage the lamp from the portion 3of the bracket, as the shoulder or sleeve 42 cannot pass through theslot 22 in the lug 2. By unscrewing the b0lt4 to the position shown inFig. III the plates 31 32 75 are permitted to slightly spring apart andthe shoulder 42 of the bolt is retracted so that the lug 2 may be raisedfrom between the plates, the body 41 of the bolt passing readily throughthe slot 22 and the lamp disengaged 8o from the bracket.

In the modified form of my device shown in Figs. V and VI of thedrawings the body 41 of the bolt extends to the head 43, the shoulder 42being omitted. A collar and en- 85 gaging lugs, as shown, or otherconvenient means are provided to prevent other than rotary motion of thebolt 4 in the plate 32. The nut 5 is shown as having a body portion, thecross-section of which is that of a cylinder 9o formed with a radialextension. The cylindric portion passes snugly through the aperture 21in the lng 2 and the extension passes intothe slot 22 in the lug. Thenut 5 passes through a suitable slot in the plate 31, so that it isrestrained from rotary and free as to longitudinal motion. f

It is clear that when the bolt is set home, as shown in full lines, Fig.VI, the lug 2 will be held firmly between the plates 31 32, the loonut-body entering the aperture 2l and being too large to pass throughthe slot 22. Loosening the bolt 4 drives the nut back to'the positionshown in dotted lines, Fig. VI, in

which position the lug 2 is easily disengaged, the slot 22 passing thebolt-body 41. It is obvious that in this construction the tongues 33 34may be omitted, the nut 5 serving to prevent relative rotation of thelug and clam ping-plate.

I am aware that many mechanical alterations may be made in my devicewithout departing from my invention and that parts of my device may beseparately used-e. g., the lugs 33 34 would be useful with the form ofbolt and nut shown in United States Patent No. 621,374 above nalned or,conversely, any other form of preventing the relative rotation of thelug 2 and the plates 3l 32 maybe used with the shouldered bolt or nutherein shown.
